Crawl Space Encapsulation & Repair

As a homeowner in Charleston, you know that the area is no stranger to humidity and rain, but you may not realize how these common occurrences affect your crawl space. Most crawl spaces use wooden beams to support the floors of your home. When excess moisture infiltrates your crawl space, it can cause these beams to experience wood rot or mold – putting your entire home at risk. Additionally, moisture in your crawl space can lead to increased energy bills, damaged insulation, and pests.  

Despite these many problem signs, Mount Valley Foundation Services has the tools and expert knowledge to keep water out of your Charleston crawl space. Crawl space repair and encapsulation involves the installation of a dehumidifier, vapor barrier, support beams, sump pump, vent covers, and more to completely waterproof your crawl space. We’ve been helping homeowners in North Carolina and South Carolina keep their crawl spaces dry since 1986, and we’re ready to help you too!

Crawl Space Problem Signs in Charleston

As mentioned, excess moisture in your crawl space leads to many problem signs below your home, especially during the rainy and humid summers in Charleston. Wood rot and mold can form on wooden beams which causes them to break down over time. As the wooden beams break down, your home may suffer from sagging floors. Mold spores may spread into your home, causing potential health problems and more mold growth. High moisture can also lead to increased energy bills as humidity travels from your crawl space and into your living area. Furthermore, the Charleston humidity attracts all kinds of pests – from insects to rodents.

Causes of Crawl Space Damage in Charleston

Obviously, moisture is the main cause of crawl space damage in Charleston, but how exactly does so much water get below your home? First, open crawl space vents allow humid air to easily penetrate the crawl space. Ineffective vapor barriers might also cause more damage if installed improperly. Another issue is over spanned floor joists that occasionally occur during construction. Essentially, these are beams that are built too far apart and are unable to support the weight of your home. Understanding these causes is the first step in repairing them!

Crawl Space Solutions

Crawl space repair and encapsulation keeps your crawl space dry and supported with many different tools. When used in tandem, these solutions offer the most efficient defense against excess moisture that any foundation company can offer. Keep moisture out with a vapor barrier and dehumidifier. After a heavy summer storm, move groundwater away from your crawl space with our internal drainage system and sump pumps. Keep your floor joists supported with our steel crawl space support beams. The best part is – all of our solutions are designed to provide a permanent fix for your crawl space!

From Jeff who initially assessed my crawlspace needs, to Damian, David, Joquise and Roderick, everyone was professional, respectful and courteous.The work included replacement of 6 cinder block peers, steel beam installation and crawl space encapsulation. The team explained their work each day and answered any questions I had about the process and materials. I had a thorough walk through upon job completion which was consistent with their process during the job.I would highly recommend Mount Valley Foundation and use them again should the need arise.

Robert Dunal and Mickeal Joe did an excellent job encapsulating our crawlspace. They are extremely professional and have an attention to detail that speaks volumes to their character and work ethic. It was great talking with them while I looked over their work as they were finishing up, and even though it was late they made sure to expend the extra effort to thoroughly inspect the seals around the door and sump pump. All the while they had nothing but good things to say about Mount Valley. These guys have really given us peace of mind with their work.Lastly, John Penn did an excellent job coming out and explaining the conditions of our crawlspace and his recommendations. It has been an overall great experience working with this company.

The customer service was great in the beginning when your company was trying to sell me a big contract but after they sold me the contract, installed the encapsulation and received payment the customer service is trash. I’ve called twice about questions pertaining to the thermostat and nobody has ever called me back. I wanted to get pictures of the finished work they did under my house and they said that was against company policy. There’s another problem I had with the installation but I don’t want to post it publicly. The work under the house was great but the customer service is awful. They really fooled me because I thought the customer service would be great for years to come but I don’t think it will if it’s a struggle to get help like it is now. The service in the beginning is nowhere near the service at the end. I hope the owner contacts me so I can fill him in on what’s happening to me. I don’t think it’s right at all.UPDATE:I am now in contact with Argie and she’s restored some of my confidence with this company. She’s attentive to my needs, concerned about what’s important to me, responds back to me in a TIMELY MANNER and treats me like she would want to be treated as a customer. If you need something done with this company contact ARGIE. THANK YOU ARGIE!!!I had my house repiped yesterday and while the guys were installing it they let me know what the installers did incorrectly while encapsulating my house. The front sump pump was full of water and not draining because it had no electrical connection. It had no electrical connection because the installers didn't even bother to plug it in. The sump pump wasn't put where it was supposed to be put according to the blueprints because the installers didn't want to dig far enough to place it in the correct spot. My front yard is full of water because the installers from Mount Valley didn't point the pipe down so it can drain properly and it's sitting vertically just filling my yard up with water. The installers left my backyard full of trash, rotted plywood, rock piles and tools when they left. They also busted my pipe in the front yard by hitting it with a shovel and left it for me to find. I appreciate you fixing it but wanted to let you know how mad I am with the installation mistakes I've found so far. I would like someone who had nothing to do with the installation come over and look at the work so I can make sure my house doesn't fall apart because things weren't done right. Please contact me when you can so I can get these things fixed.

I was having a lot of issues with my home including health issues, I first notice a crack in the Sheetrock above the corner of a window, it just kept getting larger, I also seem to have a lot of moisture under the house that was causing the installation under the floor to fall and you could see mildew and mold growing on everything under there. My and I both could smell a musty smell when the AC came on, I’m allergic to about everything and for the past 3 years I have been having constant Sinus infections, I noticed that when we went on vacation My sinus would clear up but soon as I was back home the infections started back, thats when I searched the internet and found Mount Valley Foundation Service, They sent out John Penn, he went under the house for about an hour took pictures check structure and we sat down and looked it all over well not only did I have mildew and mold and moisture problems but look like in the winter snakes would hide out in the installation, he told me what options I had and we’ll I jumped on the chance to eliminate all these issues, John new his stuff and it showed, they sent a crew out to start the work, Damion and David really did a great job at getting that job done right, I could not be anymore happier right now, I could go under there with a sleeping bag and fell clean and safe. Thanks to all the guys who came out and did the work you said you would do. I’ll try and put a few before and after pics.
